Twenty-ninth Plenary ECFA Meeting Geneva - 19 June 1981

GUIDELINES ON ECFA MEMBERSHIP and chairman's term of office


(As agreed at the 19th Plenary ECFA Meeting held on 29 March 1976)

(As amended at the 29th Plenary ECFA Meeting held on 19 June 1981
and at the 61st Plenary ECFA Meeting held on 6 June 1997
and at the 83rd Plenary ECFA Meeting held on 18 July 2008)


Long-range planning of European high-energy facilities - accelerators, large-scale facilities and equipment - adequate for the conduct of a valid high-energy research programme by the community of physicists in the participating countries and matched to the size of this community and to the resources which can be put at the disposal of high-energy physics by society. Duplication of similar accelerators should be avoided and international collaboration for the creation of these facilities should be encouraged if essential and efficient for attaining the purpose.

Equilibrium between the roles of international and national laboratories and university institutes in this research, and a close relation between research and education in high-energy physics and other fields.

Adequate conditions for research and a just and equitable sharing of facilities between physicists, irrespective of nationality and origin, as conducive to a successful collaborative effort.


To achieve these aims ECFA can engage in - among others - the following activities:

  1. regular meetings of Restricted and Plenary ECFA;
  2. ad hoc symposia and conferences sponsored or organized by ECFA;
  3. study groups, set up by ECFA, or jointly with other organizations, for special problems;
  4. demographic studies of the high-energy physics community and resources in the ECFA countries, repeated at regular intervals.
  5. monitoring of the ongoing implementation of the European Strategy for Particle Physics in the CERN Member States under activity (d), presentation of corresponding status reports to the European Strategy Session of Council.


ECFA is advisory to CERN Management, CERN Council and its Committees, and to other organizations, national or international.


Traditionally, physicists from the countries which were Members of CERN in 1966 participate in ECFA. CERN is also considered as a "country". Plenary ECFA may on request extend participation to physicists from other countries. Any participating country is free to leave ECFA on six months' notice given at a Plenary ECFA meeting. Admission of a new participating country is decided by Plenary ECFA.


ECFA consists of Plenary ECFA, Restricted ECFA, Chairman and Secretary and permanent or ad hoc working groups.


Plenary ECFA decides on all ECFA activities, appoints the Chairman and Secretary, approves the final reports of the working groups and terminates their activities, decides on admission of new countries and observers, and makes recommendations to outside organizations.

Plenary ECFA appoints members for a total maximum period of six years after nomination by their country.

While the members so chosen should be able to represent the views of the high-energy physics community of their country, they are members of Plenary ECFA as individuals. Plenary ECFA normally holds two meetings per year.

Meetings are public unless otherwise decided.


Restricted ECFA is composed of one member per country, confirmed every three years and generally appointed for at most two three-year periods . The Director-General of CERN, the Director of the Frascati National Laboratory and the Director for Particle Physics at DESY are ex-officio members.

Restricted ECFA assists and advises the Chairman and the Secretary in the current running of ECFA, and acts as the communication channel to each participating country, its physics community and national institutes and authorities.


The Chairman and Secretary are responsible for the day-to-day running of ECFA. The Secretary of elected for a three-year term.

The Chairman is elected for one term of three years which is not, normally, extendible.

Nominations for Chairman shall be invited at the second meeting of Plenary ECFA in the Chairman's second year of office and election shall take place at the first meeting the following year. The term of office shall normally start on 1st January.

The Chairman can set up ad hoc working groups and delegate to them part of his responsibility.

The Chairman acts as or appoints an ECFA observer in the committees and other organizations where ECFA is granted observer status.

The Chairman, the Secretary and the chairmen of working groups participate ex officio in the meetings of Restricted and Plenary ECFA.


Plenary ECFA may accord observer status to countries which wish to follow the work of ECFA or contribute their views on ECFA's activities. Observer status is also granted to national or international laboratories or organizations which are of importance for ECFA's activities.

Observers participate in the discussions of Restricted and Plenary ECFA unless otherwise decided for particular questions. They do not participate in decisions.
